Overview of this book

Learning how to solve natural language processing (NLP) problems is an important skill to master due to the explosive growth of data combined with the demand for machine learning solutions in production. Natural Language Processing with TensorFlow, Second Edition, will teach you how to solve common real-world NLP problems with a variety of deep learning model architectures. The book starts by getting readers familiar with NLP and the basics of TensorFlow. Then, it gradually teaches you different facets of TensorFlow 2.x. In the following chapters, you then learn how to generate powerful word vectors, classify text, generate new text, and generate image captions, among other exciting use-cases of real-world NLP. TensorFlow has evolved to be an ecosystem that supports a machine learning workflow through ingesting and transforming data, building models, monitoring, and productionization. We will then read text directly from files and perform the required transformations through a TensorFlow data pipeline. We will also see how to use a versatile visualization tool known as TensorBoard to visualize our models. By the end of this NLP book, you will be comfortable with using TensorFlow to build deep learning models with many different architectures, and efficiently ingest data using TensorFlow Additionally, you’ll be able to confidently use TensorFlow throughout your machine learning workflow.

Applications of LSTM – Generating Text

Now that we have a good understanding of the underlying mechanisms of LSTMs, such as how they solve the problem of the vanishing gradient and update rules, we can look at how to use them in NLP tasks. LSTMs are employed for tasks such as text generation and image caption generation. For example, language modeling is at the core of any NLP task, as the ability to model language effectively leads to effective language understanding. Therefore, this is typically used for pretraining downstream decision support NLP models. By itself, language modeling can be used to generate songs (https://towardsdatascience.com/generating-drake-rap-lyrics-using-language-models-and-lstms-8725d71b1b12), movie scripts (https://builtin.com/media-gaming/ai-movie-script), etc.

The application that we will cover in this chapter is building an LSTM that can write new folk stories. For this task, we will download translations of some folk stories by the Grimm...
